Sculptural blue blown glass ashtray 1960-1970

Superb vintage ashtray made of thick turquoise blown glass, probably created in the 1960s-1970s. Worked hot, its free form features four wide raised and folded movements that give the glass a particularly fluid and sculptural appearance. The variations of blue, from bright turquoise to deep blue, create beautiful plays of transparency and light. A spectacular decorative piece! Excellent vintage condition: no chips. Slight signs of use may be present.
